This shows that a file required for boot isn't there, but
this has nothing to do with the MBR stage. It's related to
what files need to be present in /boot (usually on /dev/ada0s1a,
if no specific separate boot partition has been created).

This indicates your /boot directory's content is damaged.
You proably need to reinstall its content from source, or
hope a freebsd-update will bring it back. The easiest way
to get the file probably is to copy it from the source
directory to /boot manually (directly from its location
in /usr/src).

See "man 8 menu.4th" for details.
